Today I'm hitting the small island nation of Malta. To be honest, I don't know much about Malta, other than what the wiki article says. I'm passingly familiar with the Knights Hospitaller, but other than that, I guess I'll be learning when I'm there.
From everything I've read about visiting, it's one of the few places that is actually small enough to take in on a single day. It should be interesting, and if not, at the least it'll be a relaxing day in a beautiful part of the world.
